Digital Channel 429 Rate Limiting on /api/v2/conversations/messaging

429 Too Many Requests returned on /api/v2/conversations/messaging/participants/{id}/messages with retry-after: 0.

Our AppFoundry integration handles high-volume digital routing. The standard rate limit headers are missing from the response, and exponential backoff is not resolving the queue buildup.

Is there a specific scope or configuration in the multi-tenant OAuth setup that triggers stricter throttling for programmatic message injection versus standard agent actions?

Check your OAuth scopes. The message:send scope often triggers stricter throttling than message:admin. Add a retry handler with jitter in your AppFoundry script. See KB-429-Digital-Limits for the updated rate limit tables and recommended backoff strategies.

this looks like a scope issue as mentioned above. we switched to message:admin for our legal hold exports and the 429s stopped immediately. worth checking your oauth config.
